VIMPROVEMENT IN FIRE-PROOF SFES.

' Specification forming part of Letters Patent No. 171,723, dated January 4, 1876; application iiled A November 12, 1875.

To all whom 'it may concern:

Be it known that I, WILLIAM HAGERTY, et' Monongahela (Jity, in the county of Wash- .ngton and State of Pennsylvania, have in- ;'ented a new and useful Improvement in Fire-Proof Safes; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon.

My invention relates to an improvement in fire-proof safes; and consists in constructing them in the usual form, but furnishing them with an outer and inner chamber for water, provided with inlet and outlet pipes, and communicating with each other and with double doors having waterchambers,`as hereinafter speciiied, the whole being so constructed that the several compartments or chambers for the water may be readily filled with Water, in case of tire, through the medium of watermain or other supply communicating with the inner water-chamber ofthe safe, whereby thel colder water will be in the inner cham'ber, thus affording great protection to articles within the safe. v

To enable others skilled in the art to make and use my invention I will proceed to describe its construction and operation.-

In the accompanying drawings, which form part 0f my specification, Figure l is a side elevation of a tire-proof safe. Fig. 2 is a vertical section of the same at line y of Fig. 1. Fig. 3 is a transverse section of vthe same at line y of Fig. 2.

In the drawings, A represents the outer walls of the safe. B represents the middle walls. U represents the inner walls. Between the walls A, B, and C are spaces D e, forming water-chambers. The chamber e, between the walls B and C, are supplied with water through openings f, which, by means ot' pipe or pipes, communicate with a watermain or other Water-supply. In the top wall of the chamber 6 are openings g, through which water from chamber e tlows into the chamber D, formed by the walls A and B. In the chamber D are arranged pipes h, the upper ends of which do not quite reach to the under side of the top wall of the safe, so that the water iiowing into the chamber D, after it is full, may run over and into the pipes h and be carried oft'.

'ber of small openings, j, near their upper end, so that, in. case of' the upper wall sinking down and closing the ends of the pipes, the water will ow through the small openings j and out through the pipes h.

The doors k and L are hollow, and their hinges are so constructed that the water in the chambers D and e will ow through the pintles of the hinges and communicate with the interior ot' the' doors, so that the water iiowing through the pintles of the lower hinges will pass out, after the doors are filled,

through the upper pintle ofthe hinges, thereby keeping up a complete circulation ot' wa-A ter through the doors.

Fig. 4, in an enlarged view, illustrates one way in which this may be accomplished, p r representing the two parts of the hinge, and m m the openings of the water-channel n,- but to this I make no claim.

The water owing into the. chamber e will till it, and then low from it into chamber' D, which, when full, will iiow out through pipes h, thereby keeping up a complete circulation of the water through the chambers D and e, the colder'water always being in the inner chamber e. f

The hollow spaces inthe doors la and l, communicating with the'chambers D and e, as before described, will keep up the circulation of water in them.

The pipe or pipes which communicateA with the openings f, leading to the chamber e, should be furnished with a suitable valve arranged at some point outside ot' the building in which the safe is placed, so that, in case of lire, the water may bel turned on for the purpose of iiooding', and keeping a constant flow 0i' water through the several chambers and doors hereinbet'ore described, thereby making the safe perfectly ire-proof-a desideratum long desired. d

Having thus described my improvement, what I claim as of my invention is A' safe constructed with inner and outer water-chambers e D, respectively provided with inlet and outlet pipes f h, said chambers communicating with'each other and with the doors l k, substantially as shown and described, and for the purpose specified.
